Description
Acknowledge Bit
Stores acknowledge data.
Transmit mode:
[Setting condition]
When 1 is received as the acknowledge bit when ACKE =
1 in trasmit mode.
[Clearing conditions]
•
•
Receive mode:
0: Returns 0 as acknowledge data after data reception
1: Retruns 1 as acknowledge data after data reception
When this bit is read, the value loaded from the bus line
(returned by the receiving device) is read in transmission
(when TRS = 1). In reception (when TRS = 0), the value
set by internal software is read.
When this bit is written, acknowledge data that is returned
after receiving is written regardless of the TRS value. If
bit in ICSR is written using bit-manipulation instructions,
the acknowledge data should be re-set since the
acknowledge data setting is rewritten by the ACKB bit
reading value.
Write the ACKE bit to 0 to clear the ACKB flag to 0,
bofore transmission is ended and a stop condition is
issued in master mode, or before transmission is ended
and SDA is released to issue a stop condition by a
master device.
When 0 is received as the acknowledge bit when
ACKE = 1 in transmit mode
When 0 is written to the ACKE bit
